Product details
Overview
LT1995IMS#TRPBF from Analog Devices (formerly Linear Technology) is a high-speed, gain-selectable difference/inverting/noninverting amplifier IC with integrated precision resistors. It delivers ±1000 V/µs slew rate, 32 MHz bandwidth at G=1, <0.2% gain error, and operates from ±2.5V to ±15V supplies. Used in video difference amplification, current sensing, and ATE signal conditioning where precision, speed, and configuration flexibility are critical.
For engineers reviewing the LT1995IMS#TRPBF datasheet, LT1995IMS#TRPBF pinout, LT1995IMS#TRPBF application, or LT1995IMS#TRPBF equivalent, key selection criteria include guaranteed ±85°C operation, MSOP-10 package compatibility, pin-strapped gain ranging from –7 to +8 without external components, and CMRR up to 79 dB in difference mode.
Technical Context
The LT1995IMS#TRPBF integrates a high-slew-rate op amp with eight laser-trimmed on-die resistors (1kΩ–4kΩ, 0.2% matching at 25°C), enabling precise gain configurations via pin strapping only. Its single-stage architecture avoids multi-pole compensation, supporting fast settling (100 ns to 0.1%) and wideband response.
It supports three primary topologies: difference amplifier (VOUT = G·(VPx − VMx) + VREF), inverting amplifier (VOUT = −G·VIN− + VREF), and noninverting amplifier (VOUT = G·VIN). Gain is selected by connecting P1/P2/P4 and M1/M2/M4 pins to inputs or ground - no external resistors required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Range | –7 to +8, set by pin strapping only - eliminates external resistor matching errors and layout sensitivity |
| Slew Rate | 1000 V/µs (±15V supply) - enables clean 10V step response in ≤10 ns with minimal overshoot |
| Bandwidth | 32 MHz at G=1 - supports high-fidelity video and fast transient signal conditioning |
| CMRR | 79 dB typical (G=1, ±15V) - rejects common-mode noise in motor control feedback or sensor bridges |
| Input Offset | ≤6.5 mV (I-grade, ±15V) - ensures DC accuracy in precision current sense applications |
| Supply Range | ±2.5V to ±15V - supports dual-rail industrial, test, and video systems without level-shifting |

Pinout & Package
LT1995IMS#TRPBF is housed in a 10-lead MSOP package (3mm × 3mm, 0.5mm pitch) with exposed pad internally connected to VS–. Pin 1 is P1 (noninverting gain-of-1 input); pin 10 is M1 (inverting gain-of-1 input). The package supports thermal dissipation up to θJA = 160°C/W with standard PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1 (Pin 1) | Noninverting gain-of-1 input | Connects internal 4kΩ resistor to op amp noninverting input - used for unity-gain difference or noninverting buffer |
| P2 (Pin 2) | Noninverting gain-of-2 input | Connects internal 2kΩ resistor - enables G=2, 3, 4, etc., when combined with M2 |
| P4 (Pin 3) | Noninverting gain-of-4 input | Connects internal 1kΩ resistor - key for G=4, 5, 6, 7 configurations in difference mode |
| VS– (Pin 4) | Negative supply rail | Power return path; exposed pad tied internally to this node - must be low-impedance for thermal and noise performance |
| REF (Pin 5) | Reference voltage input | Sets output DC level (e.g., ground for bipolar systems); connects internal 4kΩ resistor to noninverting input |
| OUT (Pin 6) | Amplifier output | Drives ≥30 mA into 150Ω - suitable for coaxial cable driving and active filter outputs |
| VS+ (Pin 7) | Positive supply rail | Accepts up to +15V; total supply voltage limited to 36V (VS+ to VS–) |
| M4 (Pin 8) | Inverting gain-of-4 input | Connects internal 1kΩ resistor to op amp inverting input - pairs with P4 for differential gain |
| M2 (Pin 9) | Inverting gain-of-2 input | Connects internal 2kΩ resistor - used with P2 for G=2, or with P1/P2 for G=3 |
| M1 (Pin 10) | Inverting gain-of-1 input | Connects internal 4kΩ resistor - forms matched pair with P1 for G=1 difference amplification |
Key Features
| Feature | Design Value |
|---|---|

| Laser-trimmed resistor matching | 0.2% max mismatch at 25°C, 0.3% over –40°C to +85°C - ensures stable CMRR and gain accuracy across temperature |
| High-output drive capability | ≥30 mA short-circuit current and ±13.5V swing into 1kΩ at ±15V - drives back-terminated video lines and ADC drivers directly |
| Low gain nonlinearity | 10 ppm (G=1) - preserves signal fidelity in precision instrumentation and medical imaging front-ends |
| Wide supply range support | Operates from ±2.5V to ±15V with full spec compliance - simplifies design reuse across 5V, ±5V, and ±12V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8479ARZ | Fixed G=1 difference amplifier; 200 kHz bandwidth, 80 dB CMRR @ 60 Hz; ±5V to ±500V input range | Optimized for ultra-high common-mode rejection in high-voltage current sensing, not configurable gain or video bandwidth | Select AD8479ARZ when measuring µA–mA currents across kV-level common-mode voltages - not for G>1 or >1 MHz signals |
| INA149IDR | Fixed G=1 difference amplifier; 200 kHz bandwidth, 100 dB CMRR @ DC; ±250V input range; SO-8 package | Designed for high-precision, low-drift DC measurements (e.g., battery stack monitoring), lacks speed and gain flexibility | Select INA149IDR for sub-10 ppm/°C drift and 50 µV max VOS in static sensor readouts - not for dynamic or programmable-gain needs |

FAQ
What is the maximum operating temperature range for the LT1995IMS#TRPBF?
The LT1995IMS#TRPBF is an I-grade part rated for continuous operation from –40°C to +85°C. This specification is fully guaranteed per the datasheet, with electrical parameters tested across this full range. The MSOP package's thermal resistance (θJA = 160°C/W) allows reliable operation under industrial ambient conditions when mounted on standard FR4 PCBs with adequate copper pour.
Does the LT1995IMS#TRPBF require external resistors to set gain?
No, the LT1995IMS#TRPBF does not require external resistors to set gain. It integrates eight precision laser-trimmed on-die resistors (1kΩ–4kΩ) that enable all gain configurations - including difference (G = 1 to 7), inverting (G = –1 to –7), and noninverting (G = 1 to 8) - via pin strapping only. This eliminates resistor matching errors, board space, and thermal drift concerns associated with discrete networks.
What is the typical common-mode rejection ratio (CMRR) of the LT1995IMS#TRPBF in difference amplifier mode?
The LT1995IMS#TRPBF achieves a typical CMRR of 79 dB in difference amplifier mode at G = 1 and ±15V supply, with minimum guaranteed CMRR of 65 dB. CMRR improves with higher gain settings - reaching 87 dB typical at G = 4 - due to tighter internal resistor matching and reduced sensitivity to op amp input offset. Performance is specified and tested across –40°C to +85°C.
Can the LT1995IMS#TRPBF drive a 150Ω load at ±5V supply?
Yes, the LT1995IMS#TRPBF can drive a 150Ω load at ±5V supply, delivering ±2.5V output swing with <0.25% gain error. Its output stage provides ≥30 mA short-circuit current and maintains 24 MHz full-power bandwidth at 3V peak output, making it suitable for driving back-terminated video lines, ADC input buffers, and active filters in compact 5V systems.
How does the LT1995IMS#TRPBF differ from the LT1995CDD#TRPBF?
The LT1995IMS#TRPBF and LT1995CDD#TRPBF share identical electrical specifications but differ in grade and package: LT1995IMS#TRPBF is the industrial-grade (–40°C to +85°C) version in 10-lead MSOP, while LT1995CDD#TRPBF is the commercial-grade (0°C to +70°C) version in 10-lead (3mm × 3mm) DFN. Both use the same die, but the IMS variant undergoes extended temperature testing and qualification for industrial reliability.
